SPINDLE FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 264,327, datedSeptember 12, 1882.

Application filed September 24, 1881. (No model.)

To all whom "it may concern:

Be it known that I, WALTER G. MORRISON, of Willimantic, in the county ofWindham and State of Connecticut, have invented a certain new and usefulImprovement in Spindles for Spinning-Frames, of which the following is aspecification.

The object of my invention is to provide forinclined passages leadingfrom the widest part of said cup, at points radially beyond the bolster.

mouth or edge of the cup, downward and inward, for conducting oil fromthe cup into the step,-and a bolster which has an oil cup or channel inits upper end, and the lower end of which extends downward into theoil-cup in the whirl, all as hereinafter fully described.

The accompanying drawing represents avertical section of a portion of aspinning-frame comprising my invention.

A designates the spindle. B designates the O designates the step, andDand E designate respectively the bolster and steprails, in which thebolster and step are secured by set-screws a. F designates the whirl,secured upon the spindle A in the usual way.

The upper end of the bolster B is made concave, or has an annularchannel, I), for the reception of oil; and b are holes extending fromsaid channel inward to the spindle A.

In the upper part or side of the whirl F is formed an oil cup orchamber, 0, the sides or walls of which flare outward from the mouthdownward, so that the internal form of the ch amber is conical.

mouth or edge of the cup, is a very important one, and the advantagesresulting from the use of my invention are due to this particularconstruction. When the spindle is in rotation the centrifugal force willcarry all the oil outward against the wall of the cup, and if the oilaccumulates therein to a sufficient extent it will be thrown out of themouth or over the edge of the cup by the centrifugal force. Therefore itwill be seen that if the passages c or their upperends were radiallywithi n the mouth or edge of the cup they would not be supplied withoil, for the oil would be thrown out of the mouth of the cup before ithad accumulated snfliciently to cover the upper ends of the pas sages.Where the passages are radially beyond themouth or upper edge of the cuptheir upper ends will always be covered by oil long before the oil canfly out of the cup, and the centrifugal force of the oil,'acting inconjunction with the downwardly and outwardly inclined wall of the cup,will create a pressure sufficient to force the oil through the passagesand to keep the passages clear, open, and free from dirt or sediment.

It is obvious that as the oil emerges from the lower ends of thepassages c it will be thrown outward by the centrifugal force of thewhirl, and to prevent the oil from escaping I form a projection upon theunder side of the whirl which enters the step G. This projection isproduced in this example of my invention by forming an annular groove,d, in the under side of the whirl, into which the top of the stepenters; but it is immaterial Whether the whirl projects downward outsideof the spindle (as it does when the annular groove 01 is formed) or not.

In lieu of the cup 0 being formed in the top of the whirl I it might beformed in a separate piece and carried by the whirl.

I am aware that it is not new to provide a whirl with an oil-cup flaringdownward and outward from the mouth and passages leading from said cupdownward through the whirl, and I do not claim this broadly as of myinvention. In such whirls as heretofore made, however, the upper ends ofthe passages have been radially within the mouth or upper edge of thecup, and the oil is thrown out over the mouth or upper edge of the cuplong before it covers IOO the upper ends of the passages, and hence thecentrifugal force has tended to carry and keep the oil away from thepassages instead of foreing it through the passages, as in my case.

NVhat I claim as my invention, and desire to secure by Letters Patent,is-

The combination, with the spindle A and its step, of the whirl F, havingupon or in its top an oil-eup, c, which flares outward from the mouthdownward, and having inclined passages s leading from the widest part ofthe oil-cup, at points radially beyond the mouth or upper edge of saidcup, downward and inward, for conducting oil into the step, and thebolster B, having an oil cup or channel in its upper end, and having itslower end extending downward into said whirl, substantially as and forthe purpose herein described.
